Answer:
The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.
Formation of Rainbow
Refraction, dispersion and internal reflection of sunlight are three phenomenon of light involved in formation of rainbow. It is formed due to dispersion of sunlight through water droplets. Water droplets act as small prism through which sunlight enters it refracts and disperses and then gets reflected internally which creates a rainbow in the sky which is seen to observer's eye.
you can find a diagram on Google images ..
I think it helps you

The atmospheric refraction is the phenomenon that is the reason for the twinkling of stars. The air that is present in the atmosphere is a dense fluid that is spread out over the region. It is responsible for bending of the light beam that comes through the stars.
